WILLIAM A. BRANDT, OF NEW YORK, N. Y.

SASH-PULLEY.

Application filed February 9, 1916.

To all whom it may concern:

Be it known that I, WILLIAM A. BRANDT, a citizen of the United States,and a resident of the city of New York, borough of Manhattan, in thecounty and State of New York, have invented a new and improvedSash-Pulley, of which the following is a full, clear, and exactdescription.

My invention relates to overhead sash pulleys.

An object thereof is to provide pulleys which can be secured to a windowframe without any screws.

A further object of the invention is to provide a sash pulley which canbe easily and quickly placed into position or removed when neccessary.

With the above and other objects in view, the nature of which will morefully appear as the description proceeds, the invention consists in thenovel construction, combination and arrangement of parts as herein fullydescribed, illustrated and claimed.

In the accompanying drawings, forming part of the application, similarcharacters of reference indicate corresponding 'parts in all the views.I

Figure 1 is a fragmentary section through the upper part of the windowcasing, showing the sash pulley in elevation, a portion of the pulleycarrier being broken away to show the details of construction; Fig. 2 isa longitudinal section through the window casing, the sash pulley beingshown in elevation and in a position when taken out or placed into thewindow casing; and Fig. 3 is a longitudinal section on line 33, Fig. 1.

Referring to the drawings, the sash pulley consists of a pulley housing5 and a pulley 6. The pulley housing 5 is provided with a flange 7 atthe frontwherethrough a portion of the pulley 6 projects slightly, sothat the rope going over the pulley will not bear against the flange.The housing 5'has a downwardly projecting lip 9 at the lower edge spacedfrom the flange. The face of the lip o posite the flange 7 is beveled sothat the distance between the flange and the lip decreases toward thehousing.

The pulley stile 8 is provided with a mortise 10 for admitting thehousing 5 freely Specification of Letters Patent.

therethrough. The lower edge of the mor tlse at the rear is beveled, asshown at 11, to fit the beveled side of the lip. The face of the pulleystile 8 has a recess 12 for the flange 7 which extends into the mortiseof the head 13 retaining the stile 8. The bottom of the recess 12 withinthe mortise of the head is depressed to facilitate the insertion of theflange 7 when the pulley housing 5 is placed into the stile 8.

The recess 12 at the lower end is extended far enough to seat thehousing 5 on the lower edge of the mortise 10. The flange 7 above thehousing does not project out of the mortise when the housing sits on thelower edge of the mortise 10, as shown in Fig. 3.

. The engagement of the lip 9 with the beveled edge 11 of the stiledraws the flange 7 against the stile, the weight carried by the pulley 6helping the lip 9 to draw the flange 7 into the recess 12 and preventingany accidental displacement of the sash pulley from the stile 8.

It will be noted that the lip 9 clutches the housing in the stile, andto disengage it it is necessary to move the housing 5 bodily upward tobring the lip 9 above the lower edge of the mortise 10 before the sashpulley may be removed. By pulling the lower end of flange 7 out of therecess 12, as shown in Fig. 2, the lip 9 will be out of the mortise; andby pulling downwardly on the sash pulley it may be removed entirely fromthe sash. The engagement of the flange 7 at the upper end with the head13 prevents any movement of the housing outwardly in case of a break inthe flexible member which carries the weight. That is to say, if by somemeans the window is caused to move rapidly downward it cannot pull outthe sash pulley from the stile 8. forit will be prevented, not only bythe lip 9 but also by the engagement of the flange 7 with the head 13.

I claim:

The combination with a. window casing having a pulley stile and a headfor retaining the stile, of a sash pulley comprising a pulley housingprojecting through the stile and having a predetermined verticaldisplacement in said stile, said housing having a flange projecting intothe head of the casing and adapted to retain its engagement with thehead in vertical displacement of the housing in the stile,saidhousinghaving a lip spaced from the flange for engaging the stilebetween said lip and flange when said housing is at its lowermostposition. within thestile.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
